Default RE: Surging idle sticky!!!! Here it is!!!

1. Start with the basics first, ask the EEC what is working with = DIY KOEO/KOER/Cylinder Balance Self-Test

2. Make sure your base idle is set correctly = Summarized/Corrected Base Idle Reset Procedure

3. Make sure you don't have any vacuum leaks = Engine Vacuum Leaks

4. DO NOT adjust the TPS to the mythical .9999 vdc setting, it's not required as long as the closed throttle value is between .7 - 1.0 vdc.

LUK what shows up from doing those chores.
